Kombucha Tea during Pregnancy

Does anyone know if it's safe or unsafe to drink Kombucha Tea during pregnancy?? I just discovered it and the health benefits are AMAZING based off of what I've heard and read about. But I'm not sure if it's safe for pregnancy since it is fermented tea and there are essentially good bacteria and yeast in it as well. Just figured I'd ask around before I drank a whole bottle. I did some research but I got conflicted stories.
